  1. Neuron & Supporting Cells Parts of a Synapse

  2. Neuron

  3. Synapse Synapse

  4. Supporting Cells of the CNS • Astrocyte • Microglial cells • Ependymal cells • Oligodendrocyte

  5. Astrocyte • Abundant • Clings to neurons and anchors them to blood capillaries for nutrients. http://www.benbest.com/cryonics/Astrocyte.jpg

  6. Microglial Cells • Spiderlike phagocytes that dispose of debris • Dead brain cells • Bacteria http://www.nmhct.nhs.uk/Pharmacy/images/moa-brain-pic-2.gif

  7. Ependymal Cells • Cells that line the cavities of the brain and spinal cord. http://www.octc.kctcs.edu/gcaplan/anat/Histology/ependymal2.gif

  8. Oligodendrocyte • Have extensions that wrap tightly around nerve fibers producing myelin sheaths. http://stemcells.nih.gov/StaticResources/info/scireport/images/figure81.jpg

  10. Supporting Cells of the PNS • Schwann cells • Satellite cells

  11. Schwann Cells • Form myelin sheaths around nerve fibers http://scienceblogs.com/neurotopia/upload/2006/07/neuron.png

  12. Satellite Cells • Act as protective, cushioning cells http://www.kumc.edu/instruction/medicine/anatomy/histoweb/nervous/small/Nerve07s.JPG
